b)If pressure reading is over 100 psig with compressor off, proceed to check charge level via sight glass and charge if needed.

CHARGE LOSS INDICATES A LEAK THAT MUST BE CORRECTED.

STEP 2. If a system continues to operate inefficiently after Step 1, check for moisture or dirt plugging the valve. Run the system, observing closely the gauge readings and plates temperature, noting the following.

a)If system is warm upon start-up, a DIRT-PLUGGED Valve will show an immediate deep vacuum reading on low side. Consult Sea Frost for cleaning techniques.

b)MOISTURE-PLUGGED VALVE on a properly charged system is indicated by deep vacuum readings on low side after a few minutes of operation from warm, FOLLOWED BY any combination of these symptoms:

-High side compressor discharge fitting temperature drops from hot to warm.

-Suction line from valve remains warm.

-Compressor current draw (Running amperes.) drops.

-Moisture enters either through a low side leak or during initial installation and will freeze at the valve unit, reducing or eliminating refrigeration. Turning off system and allowing the valve to warm to above freezing, then restarting, may temporarily solve the problem. If not, change RFD as follows.

STEP 3. To change a saturated RFD, allow the system to warm to ambient temperature, thereby preventing moisture from condensing in the circuit upon opening. A light bulb in the refrigerator box will speed the warming of the plates. Recover the refrigerant from system through the suction service port SLOWLY to prevent liquid and oil from escaping. " WARNING: BEFORE DISASSEMBLY OF ANY PART IN THIS SYSTEM, BE SURE CHARGE IS COMPLETELY RECOVERED. With a backup wrench holding the brass body of the Swagelok fittings loosen and back off the nuts. The tubing may be pulled out of the fittings. Remove the RFD. Replace only with an identical unit by size and color: THE SEA FROST RFD is a drier and also a receiver/filter. The desiccant and the oil in the Sea Frost RFD are special to this system and R-404a. Using the wrong oil will destroy the system.

NOTE: This system contains a measured amount of lubricating oil. Be sure the RFD being installed is a blue SEAFROST BG 2000 R-404-a RFD. Record all component exchanges in this on-board owner's manual.
